Finally, Reiser4 Benchmarks Against EXT4 & Btrfs

Phoronix: Finally, Reiser4 Benchmarks Against EXT4 & Btrfs

There is no shortage of EXT4 benchmarks from comparing this evolutionary file-system's performance on netbooks to how it battles the Btrfs file-system to its performance recession. We have even benchmarked it on USB flash drives and on high-end SSDs. We have also delivered numerous Btrfs benchmarks. In this article though we are finally delivering something that has long been requested and that is Reiser4 file-system benchmarks running directly against EXT4 and Btrfs. We have also thrown in the original ReiserFS file-system for comparison too.

fsck performance

That was an good article. Thanks.

I think it might be interesting to see the fsck performance in filesystem benchmarks likes these since it delays booting during the periodic times that it is run. Perhaps copy a several hundred gigabyte partition containing data to multiple partitions of the same size but with different filesystems and measure how long it takes fsck (using the same options that are used when it runs during boot) to complete for each one.

I know about tune2fs and the ability to turn it off but the reality is that the default state is usually to have a periodic fsck enabled. Another facet of this is that the fsck performance impacts boot performance yet most boot performance tests do not test with an fsck (as far as I have seen). Anyway, just an idea.

What I find most interesting is the performance of ext4... Never the fastest, but consistently and boringly middle of the pack.

That said, I'm not really that interested in "speed" of my file-systems, the performance metric that matters for me is how the file-system behaves when things crash: i.e. How well it preserves my data! The fastest FS in the world isn't that much use if it looses data, and as disks are slow anyway...

well, in that case you should use reiser4. Reiser4 treats the safety of your data with priority. Being atomic helps a lot.
